STORAGE DEVICE THAT POSTPONES COMPLETION OF READ COMMAND TO BEGIN EXECUTION OF A NON-READ COMMAND

摘要

A storage device includes a non-volatile storage, and a controller configured to carry out, in parallel, operations in response to a plurality of commands received from a host and queued in a command queue. When the controller receives, from the host, a read command and then a subsequent command before all data read from the non-volatile storage are transmitted to the host in response to the read command, the controller transmits a response to the subsequent command after part of the data read from the non-volatile storage are transmitted to the host and before the all data read from the non-volatile storage are transmitted to the host.
